BACKGROUND: Diabetes mellitus (DM) is one of the most common endocrine disorders affecting various physiological systems and tissues, including the reproductive organs in men. However, the consequences of DM for male individuals undergoing …

BACKGROUND: To date, there are no clear guidelines available on the treatment of adenomyosis-associated pelvic pain (AAPP); however, numerous hormonal treatments (HTs) are currently being used off-label. We conducted a systematic review and…

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology, frequently accompanied by insulin resistance, inflammation, a…

BACKGROUND: Endometrial compaction is known to positively influence pregnancy outcomes in patients with infertility undergoing assisted reproductive technology. However, the impact of endometrial compaction on pregnancy outcomes in patients…

INTRODUCTION: Endometriosis is a prevalent, estrogen-dependent, inflammatory disease that impairs fertility via hormonal dysregulation, immune dysfunction, oxidative stress/ferroptosis, genetic and epigenetic alterations, and microbiome imb…

BACKGROUND: Endometriosis is a common disease among women of childbearing age (WCBA), significantly affecting their physiological health. This study systematically analyzes the global, regional, and national burden of endometriosis in WCBA …

BACKGROUND: Evidence suggests that endometrioma cystectomy can significantly reduce ovarian reserve. Ethanol sclerotherapy is a promising, minimally invasive alternative. This overview aims to critically evaluate systematic reviews that add…
